Jerome Saltzer's "coping with complexity":

Why aren't abstraction, modularity, hierarchy, and layers enough?

  • First, you must understand what you are doing.
  • It is easy to create abstractions; it is hard to discover the right abstraction.
  • It is hard to change the abstractions later.

(ditto for modularity, hierarchy, and layers)
